From: "Darrick J. Wong" <djwong@us.ibm.com>

The aic94xx controller has a bitmask establishing which tags are ok to use
with a SATA NCQ disk.  When the queue depth is 32, however, the expression
that is used sets the mask to zero, not 0xFFFFFFFF.  This patch widens the
width of the integer so that this case is handled properly.
